If someone is affected by an evil eye, one should recite this Aayat 11 times and should be blown on the person. InshaAllah, one will be cured.
اِنۡ يَّكَادُ الَّذِيۡنَ كَفَرُوۡا لَيُزۡلِقُوۡنَكَ بِاَبۡصَارِهِمۡ لَمَّا سَمِعُوا الذِّكۡرَ وَيَقُوۡلُوۡنَ اِنَّهٗ لَمَجۡنُوۡنٌۘ ٠ وَمَا هُوَ اِلَّا ذِكۡرٌ لِّلۡعٰلَمِيۡنَ
